Which one of the following has the highest molar conductivity ?

Options

A. Diaminedichloroplatinum (II)
B. Tetraaminedichlorocobalt (III) chloride
C. Potassium hexacyanoferrate (II)
D. Hexaaquochromium (III) bromide

Answer

C

Explanation

The molar conductivity of potassium hexacyanoferrate (II) i.e., `K_(4)[Fe(CN)_(6)]` is highest because it gives maxium number of ions on ionisation.
`K_(4)[Fe(CN)_(6)] rarr 4K^(+)+[Fe(CN)_(6)]^(4-)`
